Description

Technical Field

[0001] This invention relates to the field of flash point testing technology, specifically to a steam treatment device for an open flash point tester. Background Technology

[0002] The open-cup flash point tester is used to determine the open-cup flash point value of petroleum products. It automatically corrects for atmospheric pressure and calculates the correction value. The scanning, ignition, detection, and printing of test data are completed automatically.

[0003] As the closest existing technology, Chinese Patent Publication No. CN206096007U discloses an open flash point tester, including a frame, a heating device, a sweeping device, an ignition device, an oil cup, and a temperature measuring rod assembly located on the frame. A support rod is vertically mounted on the frame, and a mounting plate is horizontally mounted on the upper end of the support rod. The temperature measuring rod assembly is mounted on the mounting plate, and a mounting ring is provided on the side wall of the mounting plate. A thermometer is vertically mounted inside the mounting ring. This solution adopts a novel mechanical structure, but in use, it presents problems that are detrimental to steam treatment.

[0004] Currently, most open-cup flash point testers test the flash point by heating the test oil, causing it to evaporate, and then igniting it. However, in actual operation, the evaporated test oil can be easily absorbed by humans, potentially causing harm and reducing the effectiveness of the intelligent open-cup flash point tester. Therefore, the evaporated vapor needs to be treated to prevent external impacts and to avoid affecting secondary measurements. Thus, an improved device is needed to address these issues. Summary of the Invention

[0005] To address the problems in the prior art, the present invention provides a steam treatment device for an open flash point tester.

[0006] The technical solution adopted by this invention to solve its technical problem is: a vapor treatment device for an open flash point tester, comprising a flash point detection structure, wherein a closed ventilated structure is fixedly connected to the outside of the flash point detection structure; a flue gas sensor is provided inside the closed ventilated structure for detecting the content of flue gas entering the closed ventilated structure per unit time; the flash point detection structure includes a detector, and a positive pressure processor for positive pressure blowing treatment of the inside of the detector is fixedly connected to the right side of the detector; the detector includes a base, a display screen and a sealing partition frame are fixedly installed on the upper surface of the base, the outer sides of the sealing partition frame are provided with protective plates, and a reactor is provided on the upper surface of the base. Located inside the sealed partition frame, the reactor has a holding tank in the middle; an ignition assembly and a temperature detection assembly are provided around the reactor; a vent hood is provided between the reactor and the ignition assembly; the outer wall of the vent hood is slidably connected to the upper surface of the base; an annular corrugated pipe is fixedly connected to the bottom of the vent hood; an elastic element is provided inside the annular corrugated pipe; an airflow vibrator is fixedly connected to the base on the inner ring of the annular corrugated pipe; guide pipes are fixedly connected to the outer sides of both the annular corrugated pipe and the airflow vibrator; the top of the airflow vibrator is fixedly connected to the bottom of the reactor through a transmission plate; symmetrical limit blocks are provided on the top of the vent hood to limit the swing amplitude of the ignition assembly.

[0007] By combining a sealed partition frame with a closed and breathable structure, the area where the reactor is located is sealed off, so that the vapors after the oil volatilizes will not be absorbed by the human body, thus ensuring human health.

[0008] By detecting the amount of flue gas passing through the closed ventilated structure per unit time using a flue gas sensor, it can be determined whether the test oil placed in the reactor is in a state of ignition or a state of low evaporation.

[0009] If the test oil is on fire, inert gas is injected into the guide pipe connected to the annular bellows, which causes the annular bellows to move the vent hood upwards from the base. The vent hood causes the ignition assembly and temperature detection assembly to separate from the burning test oil. At the same time, the vent hood forms a protective shield to prevent the flame from spreading in all directions.

[0010] If the evaporation rate of the test oil is low, the gas inside the annular bellows is drawn in through the guide pipe, causing the vent hood to lower the ignition assembly, thereby allowing the ignition assembly to process the test oil in the reactor.

[0011] Preferably, the ignition assembly includes a drive motor fixedly connected to the upper surface of the base, the output shaft of the drive motor being fixedly connected to a drive shaft, and a rotating connecting frame being axially slidably connected to the top of the drive shaft, the rotating connecting frame being located between two limiting blocks; a rotary motor is fixedly connected inside the rotating connecting frame, the output shaft of the rotary motor is fixedly connected to a lead screw, and a mounting seat that is slidably connected to the rotating connecting frame is threaded onto the outer wall of the lead screw, and an arc generator is symmetrically arranged at one end of the mounting seat facing the reactor.

[0012] By controlling the movement of the rotary motor, the lead screw can drive the mounting base to slide axially on the rotating connecting frame, thereby realizing the position adjustment of the arc device. The arc head on the arc device plays the role of ignition. The rotating connecting frame is driven by a drive motor, which is a forward and reverse motor. The rotation range of the rotating frame is between two limit blocks on the vent cover.

[0013] Preferably, both of the arc generators have a piercing part inside, the piercing part including an array of piercing heads, the top of the piercing heads being fixedly connected to the arc generator by a pop-out component.

[0014] If the evaporation rate of the test oil is low, it indicates that a large number of bubbles have accumulated on the surface of the test oil, blocking its evaporation. In this case, the rotation of the screw is controlled by the rotary motor to adjust the coverage of the electric arc device on the reactor. At the same time, the vent hood is controlled to lower the ignition assembly, so that the lower surface of the electric arc device contacts the upper surface of the reactor, allowing the puncture part to contact the bubbles accumulated on the surface of the test oil, eliminating the bubbles, and thus restoring the evaporation rate of the test oil to normal.

[0015] Preferably, the temperature detection assembly includes a vertical plate fixedly connected to the rear side of the sealing partition frame, a support frame slidably connected to the side of the vertical plate facing the reactor, a rotation adjustment shaft rotatably connected inside the support frame, and a temperature detection device fixedly installed on the outer wall of the rotation adjustment shaft by a threaded locking block, the temperature detection device being located above the reactor.

[0016] The temperature detection device performs temperature measurement, and at the same time, the temperature detection device can be rotated and adjusted with the support frame via the rotating adjustment shaft, which facilitates positioning and adjustment.

[0017] Preferably, the positive pressure processor includes a docking communication main pipe that is fixedly connected to a protective plate on the right side of the sealing partition frame and is symmetrically arranged. The air outlet of the docking communication main pipe is higher than the top of the reactor. A ventilation duct seat is fixedly connected to the end of the docking communication main pipe away from the sealing partition frame. The ventilation duct seat is in communication with the docking communication main pipe. A communication frame seat is fixedly connected to the bottom of the ventilation duct seat. A positive pressure processing part that communicates with the ventilation duct seat is provided inside the communication frame seat.

[0018] Preferably, the positive pressure treatment unit includes a conical guide channel fixedly connected to the top of the connecting frame seat, the conical guide channel communicating with the ventilation duct seat, a symmetrically arranged vent pipe opening fixedly connected to the lower end of the conical guide channel, a vent valve provided on the outer wall of each vent pipe opening, a push rod slidably connected inside each vent pipe opening, a push platform fixedly connected to the bottom of the push rod, a push hinge seat fixedly connected to the bottom of the push hinge seat, a hinge link frame hinged to the bottom of the push hinge seat, the hinge link frame being driven and connected by a drive eccentric rod, a drive chain fixedly connected to the side end of the drive eccentric rod, and a motor installed on the side end of the drive chain.

[0019] The electric motor drives the drive chain to rotate, which in turn drives the drive eccentric rod to move, thereby adjusting the position of the articulated connecting rod frame. The articulated connecting rod frame then drives the push articulated seat to move, thereby changing the position of the push rod and the push platform. This causes the push rod to squeeze the vent pipe opening, guiding the gas through the conical guide channel for discharge processing.

[0020] Preferably, the drive eccentric rod is located at the eccentric position of the drive chain, and the motor drives the hinged connecting rod frame and pushes the hinged seat to reciprocate through the drive chain and the drive eccentric rod.

[0021] Preferably, the closed and breathable structure includes a purifier disposed on the rear side of the base. The top of the purifier is fixedly connected to an array of guide channels. The top of the guide channels is fixedly connected to a negative pressure generator. The side of the negative pressure generator is fixedly connected to the top of the vertical plate via a connecting guide seat. The air intake of the negative pressure generator passes through the connecting guide seat and faces the reactor. The top of the connecting guide seat is fixedly connected to a sealing frame. A barrier cover is hinged inside the sealing frame via a hinge. The end of the sealing frame away from the connecting guide seat is fixedly connected to the front end of a sealing partition frame. The barrier cover is fixedly snapped into the end of the sealing frame away from the connecting guide seat via a snap-fit ​​frame. The flue gas sensor is disposed inside the air intake of the negative pressure generator.

[0022] Preferably, a protective plate is fixedly connected to the side of the sealing frame facing the sealing partition frame, and the end of the protective plate away from the sealing frame is fixedly connected to the sealing partition frame.

[0023] By installing a protective plate between the sealing frame and the sealing partition frame, the enclosure of the reactor by the closed and breathable structure is improved, further preventing the vapors from the test oil from harming the human body.

[0024] Preferably, the base is further provided with a humidity regulator, and the front end of the humidity regulator is connected to a humidity regulating conduit.

[0025] By connecting the humidity regulating conduit and humidity regulator to an external water source, the ambient humidity inside the closed and breathable structure and the flash point detection structure can be adjusted, thereby enabling the acquisition of simulated test data, better conducting simulation tests, and improving the accuracy of the test data.

[0026] The beneficial effects of this invention are:

[0027] 1. This invention facilitates flash point data detection through the structural design of the detector. The lead screw can be driven to rotate, thereby changing the position of the mounting base on the rotating frame. Ignition is performed by an arc generator. The mounting base can control the angle of the temperature detector, thus realizing the temperature detection function at a fixed position. At the same time, the positive pressure processor can perform positive pressure processing, so that the internal structure of the sealed and breathable structure and the flash point detection structure can form a stable environment and reduce external interference.

[0028] 2. The present invention facilitates specific positive pressure processing work through the structural design of the positive pressure processing unit. The motor is started, and the motor can control the drive chain and drive the eccentric rod to rotate. When the eccentric rod rotates, it can drive the hinged connecting rod frame and push the hinged seat to move in coordination, thereby pushing the push rod and the push platform to move and adjust on the vent. The vent has a groove to allow air to be drawn in. Through compression, the gas is made to pass through the vent to the cone guide channel for centralized conduction processing.

[0029] 3. This invention determines whether the test oil placed in the reactor is in a state of ignition or a state of low evaporation by detecting the content of flue gas passing through the closed ventilated structure per unit time. If the test oil is in a state of ignition, the ventilated hood causes the ignition component and temperature detection component to separate from the burning test oil, and at the same time, the ventilated hood forms a protective shield to prevent the flame from spreading in all directions. If the test oil has a low evaporation rate, the gas inside the annular corrugated pipe is drawn in through the guide pipe, causing the ventilated hood to lower the ignition component, thereby allowing the ignition component to process the test oil in the reactor.

[0047] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0048] Reference Figures 1 to 15 A vapor treatment device for an open flash point tester includes a flash point detection structure 1, with a closed ventilated structure 4 fixedly connected to the outside of the flash point detection structure 1; a flue gas sensor is provided inside the closed ventilated structure 4 for detecting the content of flue gas entering the closed ventilated structure 4 per unit time; the flash point detection structure 1 includes a detector 2, with a positive pressure processor 3 fixedly connected to the right side of the detector 2 for positive pressure blowing treatment inside the detector 2.

[0049] The detector 2 includes a base 201. A display screen 202 and a sealing partition frame 203 are fixedly installed on the upper surface of the base 201. The outer side of the sealing partition frame 203 is provided with a protective plate 204. A reactor 205 is provided on the upper surface of the base 201. The reactor 205 is located inside the sealing partition frame 203. A holding tank 206 is provided in the middle of the reactor 205.

[0050] An ignition assembly 5 and a temperature detection assembly 6 are provided around the reactor 205. A vent 7 is provided between the reactor 205 and the ignition assembly 5. The outer wall of the vent 7 is slidably connected to the upper surface of the base 201. An annular bellows 8 is fixedly connected to the bottom of the vent 7. An elastic element is provided inside the annular bellows 8. An airflow vibrator 9 is fixedly connected to the base 201 in the inner ring of the annular bellows 8. Guide pipes 10 are fixedly connected to the outer sides of both the annular bellows 8 and the airflow vibrator 9. The top of the airflow vibrator 9 is fixedly connected to the bottom of the reactor 205 through a transmission plate 11.

[0051] The top of the vent 7 is symmetrically provided with limiting blocks 12 for limiting the swing amplitude of the ignition assembly 5.

[0052] By combining the sealing partition frame 203 with the closed and breathable structure 4, the area where the reactor 205 is located is sealed off, so that the vapors after the oil volatilization will not be absorbed by the human body, thus ensuring human health.

[0053] The flue gas sensor in the closed ventilated structure 4 detects the flue gas content passing through the closed ventilated structure 4 per unit time to determine whether the test oil placed in the reactor 205 is in a state of ignition or the test oil evaporation rate is in a state of low evaporation.

[0054] If the test oil is on fire, inert gas is injected into the guide pipe 10 connected to the annular bellows 8, which causes the annular bellows 8 to move the vent 7 upwards towards the base 201. The vent 7 causes the ignition assembly 5 and the temperature detection assembly 6 to separate from the burning test oil. At the same time, the vent 7 forms a protective shield to prevent the flame from spreading in all directions.

[0055] If the evaporation rate of the test oil is low, the gas inside the annular bellows 8 is drawn in through the guide pipe 10, causing the vent 7 to drive the ignition assembly 5 to descend, thereby allowing the ignition assembly 5 to process the test oil in the reactor 205.

[0056] Specifically, the ignition assembly 5 includes a drive motor 501 fixedly connected to the upper surface of the base 201. The output shaft of the drive motor 501 is fixedly connected to a drive shaft 502. The top of the drive shaft 502 is axially slidably connected to a rotating connecting frame 503, which is located between two limiting blocks 12. A rotary motor is fixedly connected inside the rotating connecting frame 503. The output shaft of the rotary motor is fixedly connected to a lead screw 504. A mounting seat 505 that is slidably connected to the rotating connecting frame 503 is threaded onto the outer wall of the lead screw 504. An arc generator 506 is symmetrically arranged at one end of the mounting seat 505 facing the reactor 205.

[0057] By controlling the movement of the rotary motor, the lead screw 504 can drive the mounting base 505 to slide axially on the rotating connecting frame 503, thereby realizing the position adjustment of the arc generator 506. The arc head on the arc generator 506 plays the role of ignition. The rotating connecting frame 503 is driven by the drive motor 501, which is a forward and reverse motor. The rotation range of the rotating frame is between the two limit blocks 12 on the vent cover 7.

[0058] Specifically, both arc generators 506 have a piercing part 13 inside. The piercing part 13 includes piercing heads 1301 arranged in an array. The top of the piercing heads 1301 is fixedly connected to the arc generator 506 through a pop-out component 1302.

[0059] If the evaporation rate of the test oil is low, it indicates that a large number of bubbles have accumulated on the surface of the test oil, blocking its evaporation. At this time, by controlling the rotary motor to drive the lead screw 504 to rotate, the coverage area of ​​the electric arc device 506 on the reactor 205 is adjusted; at the same time, the vent 7 is controlled to drive the ignition assembly 5 to descend, so that the lower surface of the electric arc device 506 contacts the upper surface of the reactor 205, and the puncture part 13 contacts the bubbles accumulated on the surface of the test oil, eliminating the bubbles and restoring the evaporation rate of the test oil to normal.

[0060] Specifically, the temperature detection component 6 includes a vertical plate 601 fixedly connected to the rear side of the sealing partition frame 203. A support frame 602 is slidably connected to the side of the vertical plate 601 facing the reactor 205. A rotation adjustment shaft 603 is rotatably connected inside the support frame 602. A temperature detection device 604 is fixedly installed on the outer wall of the rotation adjustment shaft 603 by a threaded locking block. The temperature detection device 604 is located above the reactor 205.

[0061] The temperature detection device 604 performs temperature measurement. At the same time, the temperature detection device 604 can be rotated and adjusted with the support frame 602 via the rotating adjustment shaft 603, which facilitates positioning and adjustment.

[0062] Specifically, the positive pressure processor 3 includes a docking communication main pipe 301 that is fixedly connected to the protective plate 204 on the right side of the sealing partition frame 203 and is symmetrically arranged. The air outlet of the docking communication main pipe 301 is higher than the top of the reactor 205. A ventilation duct seat 302 is fixedly connected to one end of the docking communication main pipe 301 away from the sealing partition frame 203. The ventilation duct seat 302 and the docking communication main pipe 301 are interconnected. A communication frame seat 303 is fixedly connected to the bottom of the ventilation duct seat 302. A positive pressure processing part 304 that communicates with the ventilation duct seat 302 is provided inside the communication frame seat 303.

[0063] Specifically, the positive pressure treatment unit 304 includes a conical guide channel 3041 fixedly connected to the top of the connecting frame seat 303. The conical guide channel 3041 is interconnected with the ventilation duct seat 302. The lower end of the conical guide channel 3041 is fixedly connected to symmetrically arranged vent pipes 3042. Each vent pipe 3042 is provided with a vent valve 3043 on its outer wall. Each vent pipe 3042 is slidably connected to a push rod 3044. The bottom of the push rod 3044 is fixedly connected to a push platform 3045. The bottom of the push platform 3045 is fixedly connected to a push hinge seat 3046. The bottom of the push hinge seat 3046 is hinged to a hinge link frame 3047. The hinge link frame 3047 is driven and connected by a drive eccentric rod 3048. The side end of the drive eccentric rod 3048 is fixedly connected to a drive chain 3049. The side end of the drive chain 3049 is equipped with a motor.

[0064] The electric motor drives the drive chain 3049 to rotate, which in turn drives the drive eccentric rod 3048 to move, thereby adjusting the position of the hinged connecting rod 3047. The hinged connecting rod 3047 then drives the push hinge seat 3046 to move, thereby changing the position of the push rod 3044 and the push platform 3045. This causes the push rod 3044 to squeeze the vent 3042, guiding the gas through the conical guide channel 3041 for discharge processing.

[0065] Specifically, the drive eccentric rod 3048 is located at the eccentric position of the drive chain 3049. The motor drives the hinged connecting rod frame 3047 and pushes the hinged seat 3046 to reciprocate through the drive chain 3049 and the drive eccentric rod 3048.

[0066] Specifically, the closed and breathable structure 4 includes a purifier 401 located on the rear side of the base 201. The top of the purifier 401 is fixedly connected to an array of guide channels 402. The top of the guide channels 402 is fixedly connected to a negative pressure generator 403. The side of the negative pressure generator 403 is fixedly connected to the top of the vertical plate 601 via a connecting guide seat 404. The air intake of the negative pressure generator 403 passes through the connecting guide seat 404 and faces the reactor 205. The top of the connecting guide seat 404 is fixedly connected to a sealing frame 405. The inside of the sealing frame 405 is hinged to a barrier cover 406. The end of the sealing frame 405 away from the connecting guide seat 404 is fixedly connected to the front end of the sealing partition frame 203. The barrier cover 406 is fixedly snapped to the end of the sealing frame 405 away from the connecting guide seat 404 via a bayonet frame 407.

[0067] The flue gas sensor is located inside the intake port of the negative pressure generator 403.

[0068] Specifically, a protective plate 204 is fixedly connected to the side of the sealing frame 405 facing the sealing partition frame 203, and the end of the protective plate 204 away from the sealing frame 405 is fixedly connected to the sealing partition frame 203.

[0069] By setting a protective plate 204 between the sealing frame 405 and the sealing partition frame 203, the enclosure of the reactor 205 by the closed and breathable structure 4 is improved, further avoiding the harm to the human body caused by the vapors of the test oil.

[0070] Specifically, the base 201 is also equipped with a humidity regulator 14, and the front end of the humidity regulator 14 is connected to a humidity regulating conduit 15.

[0071] By connecting the humidity regulating conduit 15 and the humidity regulator 14 to an external water source, the ambient humidity inside the closed and breathable structure 4 and the flash point detection structure 1 can be adjusted, thereby enabling the acquisition of simulated test data, better conducting simulation tests, and improving the accuracy of the test data.

[0072] An electric heating wire is embedded inside the reactor 205; the heating wire is electrically connected to an external power source; the elastic element is a spring; the ejector element is an electromagnetic pin; the protective plate 204 is made of a transparent material, such as tempered glass or high-temperature resistant acrylic sheet. The display screen 202 houses a control system that controls the electrical components inside the device.

[0073] In the initial state, the electric heating wire is not working, the annular corrugated pipe 8 does not expand, and the top of the vent 7 is at the same height as the top of the reactor 205.

[0074] Since the barrier cover 406 is hinged to the sealing frame 405, during use, the tester first lifts the barrier cover 406, and then places the Cleveland open cup containing the test oil into the holding tank 206 inside the reactor 205. Because the inner diameter of the vent 7 is larger than the outer diameter of the reactor 205, there is a gap between the vent 7 and the reactor 205. In the initial state, the rotating connecting frame 503 is in contact with the top of the vent 7, and the side of the rotating connecting frame 503 is in contact with the limiting block 12. This ensures that when the Cleveland open cup is placed in the holding tank 206 inside the reactor 205, the rotating connecting frame 503 will not obstruct the Cleveland open cup. After placement, the temperature detection device 604 on the support frame 602 is placed inside the Cleveland open cup, and then the barrier cover 406 and the sealing frame 405 are locked together by the bayonet 407. The preliminary preparation work is then completed.

[0075] The control system controls the guide pipe 10, which is connected to the annular bellows 8, to inject inert gas into the annular bellows 8. This causes the annular bellows 8 to push the vent 7 upward. Since the top of the vent 7 is in contact with the rotating connecting frame 503, the rotating connecting frame 503 is simultaneously moved upward as the vent 7 moves upward. This causes the rotating connecting frame 503 to separate the electric arc generator 506 from the top of the reactor 205. After the vent 7 and the rotating connecting frame 503 rise to a position 12-16 mm above the reactor 205, the control system stops injecting inert gas into the annular bellows 8. Then, the control system controls the guide pipe 10, which is connected to the airflow vibrator 9, to operate, causing the airflow vibrator 9 to vibrate. The airflow vibrator 9 transmits the vibration to the reactor 205 through the transmission plate 11, thereby causing the Cliff... The test oil in the Cleveland open cup vibrates synchronously, causing the air bubbles in the test oil to gradually move to the surface of the test oil under the influence of the airflow vibrator 9 and gradually burst. The control system controls the operation of the airflow vibrator 9 and simultaneously controls the heating wire to heat the test oil in the Cleveland open cup through the reactor 205. At the same time, the control system detects the temperature of the test oil in the Cleveland open cup through the temperature detection device 604. When the test oil temperature reaches 60°C before the expected flash point, the control system adjusts the heating rate of the heating wire to the Cleveland open cup so that when the test oil temperature reaches 40°C before the flash point, the heating rate can be controlled to increase by 3±1°C per minute. At the same time, the control system adjusts the vibration amplitude of the airflow vibrator 9 to ensure that the airflow vibrator 9 does not affect the evaporation rate of the test oil in the Cleveland open cup.

[0076] While heating the Cleveland open cup, the control system simultaneously activates the positive pressure processor 3 and the negative pressure generator 403. The positive pressure processor 3 delivers a mixture of inert gas (helium) to the interior of the sealed partition frame 203. The negative pressure generator 403 draws the mixture delivered to the interior of the sealed partition frame 203 and the steam generated during the oil heating process into the purifier 401 through the guide channel 402. The purifier 401 filters and discharges the steam to prevent the steam from being absorbed by the human body after the oil evaporates, thus ensuring human health.

[0077] When the positive pressure processor 3 is working, the control system controls the positive pressure processing unit 304 to start, and the control system controls the motor to drive the motor. The motor drives the drive chain 3049 to rotate. Since the drive eccentric rod 3048 is located at the eccentric position of the drive chain 3049, during the rotation of the drive chain 3049, the drive chain 3049 drives the drive eccentric rod 3048 to move, thereby adjusting the position of the hinged linkage frame 3047. The hinged linkage frame 3047 drives the push hinge seat 3046 to move up and down reciprocally. During the upward movement of the push hinge seat 3046, the push platform 3045 drives the push rod 3044, causing the push rod 3044 to squeeze the vent pipe. The push rod 3044 delivers the mixed gas in the vent 3042 through the conical guide channel 3041 to the ventilation duct seat 302. The mixed gas in the vent 3042 is introduced by the vent valve 3043. The ventilation duct seat 302 guides the gas into the connecting main pipe 301 and delivers it from the outlet of the connecting main pipe 301 to the interior of the sealing partition frame 203. Since the outlet of the connecting main pipe 301 is higher than the top of the reactor 205, and the airflow ejected from the outlet of the connecting main pipe 301 is in a certain proportion to the rate of oil evaporation, the steam evaporated from the oil will not affect the final detection effect while ensuring human health.

[0078] It should be noted that the purpose of the positive pressure processor 3 in this device is to prevent the air in the closed area formed by the closed ventilated structure 4 and the sealed partition frame 203 from being drawn into the purifier 401 due to the negative pressure generator 403 being constantly in operation. This would cause the temperature detection device 604 to detect inaccurate values ​​when the ignition assembly 5 is performing an open flash point test.

[0079] During the open flash point test of the test oil, the outlet of the connecting pipe 301 in this device is located above the Cleveland open cup, and the direction of the mixed gas discharged from the outlet of the connecting pipe 301 is from the outlet of the connecting pipe 301 towards the sealing frame 405. Therefore, when the positive pressure processor 3 is working, it will not affect the test oil vapor located below the outlet of the connecting pipe 301. Due to the lighter weight of the inert gas (helium), after the inert gas (helium) is ejected from the outlet of the connecting pipe 301, it will float directly upwards and mix with the vapors of the test oil. After the steam is mixed, it is drawn into the purifier 401 by the negative pressure generator 403. The amount of gas ejected by the positive pressure processor 3 is in a certain proportion to the amount of gas drawn into the negative pressure generator 403, so that the air in the closed area formed by the closed ventilated structure 4 and the sealed partition frame 203 is kept in a balanced state. This avoids the phenomenon that the temperature detection device 604 detects the inaccurate value when the ignition component 5 is tested for the open flash point because the negative pressure generator 403 is always in working state after the closed ventilated structure 4 and the sealed partition frame 203 seal the area where the reactor 205 is located.

[0080] When the oil temperature reaches 10°C before the expected flash point, the control system controls the drive motor 501 and the arc generator 506 to operate. The drive motor 501 drives the rotating connecting frame 503 to rotate via the drive shaft 502. The rotating connecting frame 503 drives the arc generator 506 to reciprocate between the two limit blocks 12 on the vent 7 via the mounting base 505. During the oscillation, the arc head on the arc generator 506 passes through the center of the reactor 205. The time for one oscillation of the arc generator 506 is 2-3 seconds. When the blue flame first appears above the oil, the temperature value recorded by the temperature detection device 604 is immediately recorded. This value is the result of the flash point determination.

[0081] Finally, the test data is displayed on screen 202, after which the control system returns the electrical components to their initial state. The user then resets the sealed ventilated structure 4 and the flash point detection structure 1, thus completing the flash point test.

[0082] During the flash point test of the test oil, the vapor emitted by the test oil forms a flammable mixture with air, which can ignite upon encountering an ignition source. Combustion at this flash point temperature cannot be sustained, but if the temperature of the test oil continues to rise, it may cause the test oil in the Cleveland open cup to ignite. As the positive pressure processor 3 and the negative pressure generator 403 operate, the control system detects the amount of flue gas entering the intake port of the negative pressure generator 403 per unit time through the flue gas sensor to determine whether the test oil placed in the reactor 205 is in a state of ignition. If the detected value is higher than the set value, it indicates that the test oil is in a state of ignition. At this time, the control system controls the electric heating wire to stop heating, and at the same time, the control system injects inert gas into the guide pipe 10 connected to the annular bellows 8. The guide pipe 10 guides the inert gas into the annular bellows 8, causing the annular bellows 8 to expand again, thereby causing the annular bellows 8 to move the vent 7 further upwards towards the base 201. Since the rotating connecting frame 503 is restricted between the two limit blocks 12 on the vent 7, Furthermore, the temperature detection device 604 is located inside the Cleveland open cup. As the annular bellows 8 drives the vent 7 to rise, it simultaneously drives the rotating connecting frame 503 and the temperature detection device 604 to rise until the temperature detection device 604 is no longer in contact with the flame generated by the test oil. Simultaneously, as the vent 7 rises, the vent covers the reactor 205, forming a protective shield to prevent the flame from spreading. Since the positive pressure processor 3 is in operation at this time, the air outlet of the connecting main pipe 301 is higher than the top of the reactor 205, and the vent valve 3043 on the vent pipe 3042 is connected to an internal gas source containing inert gas. Once the temperature detection device 604 is no longer in contact with the flame generated by the test oil, the control system controls the positive pressure processor 3 to quickly fill the sealed partition frame 203 with a large amount of inert gas, such as helium. The inert gas entering the sealed partition frame 203 passes through the mesh on the vent 7 and enters the vent 7, extinguishing the flame generated by the test oil.

[0083] When the control system detects that the amount of flue gas entering the suction port of the negative pressure generator 403 per unit time is lower than the amount of flue gas produced by the evaporation of the test oil at the corresponding temperature, it indicates that the test oil contains a certain amount of water. Therefore, when the test oil is heated, the water dispersed in the test oil will form bubbles and cover the liquid surface, affecting the normal vaporization of the test oil. At this time, the control system controls the guide pipe 10 connected to the annular bellows 8 to perform a suction operation on the annular bellows 8, causing the annular bellows 8 to contract. Because the rotating connecting frame 503 is restricted between the two limit blocks 12 on the vent 7, and the rotating connecting frame 503 is slidably connected to the drive shaft 502, when the guide pipe 10 performs the suction operation on the annular bellows 8, the vent 7 drives the rotating connecting frame 503 to move downwards, causing the rotating connecting frame 503 to contact the top of the Cleveland open cup. Then, the control system controls the rotary motor to drive... The lead screw 504 rotates, and the lead screw 504 adjusts the coverage area of ​​the arc generator 506 on the Cleveland open cup through the mounting base 505. When the coverage area of ​​the arc generator 506 on the Cleveland open cup is greater than the diameter of the reactor 205, the control system simultaneously controls the reciprocating extension and retraction of the ejector and the reciprocating rotation of the drive motor 501. The ejector drives the piercing part 13 to contact the bubbles accumulated on the surface of the test oil, so that the piercing part 13 pierces the bubbles accumulated on the surface of the test oil. During the reciprocating rotation of the drive motor 501, the rotating connecting frame 503 is simultaneously driven to reciprocate between the two limiting blocks 12 on the vent 7. The rotating connecting frame 503 drives the arc generator 506 and the piercing part 13 to eliminate the bubbles on the Cleveland open cup in all directions, so as to avoid the phenomenon that too many bubbles accumulate on the surface of the test oil, which would prevent the test oil from evaporating normally and causing the test oil to overflow out of the cup, thus making the test impossible to carry out.
